APPARATUS FOR AND METHOD OF SIML'IANEOSLY TEX'LURING BOTH ENDS OF l BRICKS.

Application iled December 16, 1925.V Serial No. 75,762.

This invention relates to devices and processes of texturing the ends of bricks by texturing the edges of the plastic clay column from which the bricks are cutl and refers more particularly to a process of crummy texturing the ends of building brick whilethey are being similarly textured on a side surface. Y

yAmong the salientobjects of this invention areto provide a device whereby in the process of manufacture of building bricks the edges of the plastic clay column may each be simultaneously textured while the top of the column is being textured with a surface of similar appearance. i

A particular object of my invention is to provide not only a means of combing or scratching the surface of the plastic column .but a means ofv saving the clay` crumbs scratched up off of the top surface with the scratchers, and forciblyv blowing them against androlling them into the edge of the clay ycolumn in such a way as to make the surface of the edge of the plasticclay column looklike the top face of the column does after it has been scratched and rolled to get a crummy texture.

' Iv attain thev objects of my invention by the device described in detail in the annexed specifications, recited in the claims and illus'tratcd in thev accompanying drawings, in which the numerals representing detailed parts of the device will be the saine repre-j senting like parts in the several'gures.

l v In the drawings Figure -1 is a plan view of the apparatus. .Figure 2v is one side elevation of the apparatus showninFig l. f

Figure 3 is a detail illustrating the scraper and the mannerof its mountingused for scraping theplastic'clay crumbs off of the top of the clay column after theyhavebeen scratched up from the surface where they drop into hoppers in a blower pipe from wherev they are blown and rolled into the edges ofthe clay column.

iFigure a -is a detail showing the manner in which the plastic clay crumbs are forcibly blown Vagainst and rolled into the sides ofv theV plastic clay'column to make them look like the top surface of the clay column after it 'has been scratched and` rolled.

LFigure is a ydetail showing the method of mountingthe' side rollers which rollv the plastic clay crumbs into the edges of the clay column.

Figure 6 is a detail'cut-away showing'the hopper inthe blower pipe with its valve adapted to ladmitfthe air through the hopper 'without the loss of air outy the hopper opening when the blower is'in operation.

Figure 7 is a perspective of a brick as' well asa sectionA of the column from which the brick is cut showing in more complete detail the appearance vof the surface' texture on the face and ends of the brick made possible through my invention.

A careful study of the drawingsy will'replastic clay column by merely scratching the surface with a scratcher or wire comb after which the plasticV crumbs of clay that are scratched out of the surfacel are immediatelyrolled iny their roughened condition back into the surface, which results in leaving thetop surface of the clay columnv ina rough spongy looking appearancevin texture. i

`To those who are skilled in the art of brick manufacturing it will be seen that vthe method of crummy texturing the top surface of the plastic clay columnby scratching and rolling as described is one Ythat has been in use for some time in our own factoryy and perhaps'in others and the detailsv of the apparatus for accomplishing thisresult are not claimed herein as new but'when it comes to similarly texturing the ends of brick. or the sides of they plastic claycolumn before the bricks are cut therefrom a problem arises which heretofore has givenmuch concern to manufacturers of bricks forv instance:

In order that a brick should be success- At the present time when the old method of crumniy texturing the top surface of the plastic clay column is in operation the i und side operation in an V.l'i'lllowez- As the plastic clad'Y column -lemerges;

from the die Nm under prei-sure the top snr'li'uc thcreol immediatelyY be come scratched combed ou the iop snrl'facc by ecratcher Mo-W and on the :fiile eurfaces by scratchcrlil v1-lm :ind -5- rcepectirely and by referring to Fig. l it Will readily be seen that the cia3' cruelle clutched oil' by Seratchers land 5- i lll at once drop oliI on the lloor but that the crumbs sifratched up by ecratcher millieine' on the top Surlnce will not be lost but will be available ilor use, .in rolling` [hein into the side surliacv to malte thc Sider; et the clay colunni lool( like the top surface doen1 ailier it has been scratched and rolled.

To accomplish this result lf provide a V shaped scraper ha secured to scratcher Aiwn'hich in adopted to scrape crunibl -T-- oil' ol" the 'lop of the column in approximately eren miantii'ics olli' over each et the Sides where :laid crumbs lull into hoppers r3-- and MQW reapectively olf blower pince 10M and -lirespectively. Blowers w#l2- and ---ll posiiiiiined on opposite sides oiE the cle.)- column and die when in operation are adapted to torce a very strong; draft oi air through blower pipes; lO- and miii-- rcepectireljy and es the;7 do eo the crumbs which fall into hoppen; -Qi and --ll-- are autoniaticallgr iorced with decided speed out the respective ende of blower pipes; will and LLM directly under the liront ol rollers -ll1- and, l5 respectively juist these rollers normally1r come into .irni contact with the sides` oi the cle)v column where it will thus be seen that the plastic clay crunibe raken 'from the top Surface ol? the cla;v column ere forcibl;7 blown against and iiruil)V rolled into the opposite Sides o'l3 the clay column bollore they over have fi chance to drop to the licor. Numerale 30W and -llindicate blow erri actuated by motore.

lt will be observed that it onliv one scratelier 3M were provided 'tor the lop surface of the clog' column and then crumbe -T-H were need 'lor the eide as han been described that the proccee ol tenturiinr the top Surface would not be ccoiniilislied com- Pietel; f but l provide other eeraichere :incl rollere to iiollow them further on down the column oil clay which amply accoinplisli the proceed of crununj)- torturing the top surface of the cia3,7 column.

llor instance as; the clay column moves aloneoul oi die 2M it lin-t passes under scratcher and. effrayer 45H where the riunire -T that have been scratched up by rcrul'cher --lure raked oli' the top o l the clay colunni wif-AA- u'here they are clisnofed ol" as above described in the normal operation olf the device ol un' nivention; but alter the clay column lhas moved beyond the if shaped Scraper G- it is necesa rj: lo u ojuln scratch lhc ion surilzice thereof in order lo work up the pli-lelie clay crumbs nece earn For cruninii terlzuring the top sur- :iirc ol? hc column.

il `will be neen therefore, that a Second :wm-:richer M---iiifuugpcirted by u bracket 2- i111 nriwideil to: again scratchingr the 1^ ce o li column `-l and when plastic cruuihl` are thus again Worked out o ihc iop uurlace of the column these crumbs Wlfl--M are lirnilj; rolled into the top surilu-iwi the column again by roller i9 lhue` termini! a crunnny` epongy appearinzc; texture For this Sur'luce oit the col umu. nriliingr a seur'lace oil pleaeing appear- :ince and one that will thus match the tex iure oi the "ciro Sides oi the chi): column alter ihr cruuuny texture has been made on tl'ieee elders by the device oi" my invention.

lt will be eeen that all'er this clay column cui up into bricks that each brick will have one lace and each end `all of similar texture oi a rough erunnny spongy appeal ance, :i result made possible economically` conveniently, and quickly` in the process of inanui'mzture in the normal operation ol' the device oil my invention.

It. Will he Seen that rollers *14T* and l5- are pivotallyT mounted in a cleViS 20- and m21- Which is pivotally mounted on an upright rod -22- and --23-. This rod Supported by bearingr *2lifor belt pulley -25- and `it will also be Seen that` roller -19- :is supported on bracket *QG* which holds said roller firmly in contactA with the top surface of column 1- through the tensile strain of spring -27.

ln connection with hoppers Jland --l,loil the blower pipe lllm and -11- respectively a one Way valve -28 and *29M ie need as :i sort of flap valve for controlling or directingl the course ol. the

air straight through the bottom of hopper -8- and -9-, respectively. Numeral 32 indicates a bracketed metallic plate adapted to substantially support comb-ing device -3- and the scraping device -6-. (See Fig. -3`-.)

Having thus described the nature of my invention what I claim is: Y

l. A device for simultaneously texturing both ends of brick comprising in combina.- tion a surface comb for the top surface of the green clay column as the same is discharged from the forming die; a V shaped scraper operatively connected to said comb and adapted to scrape the clay crumbs off ofthe surface that are scratched up by `said comb; Va pair of oppositely disposed combs for scratchingl the edges of said clay column; a pair of oppositely disposed surface rollers spacedfrom said combs for the edge and a pair of blowers having blow `pipes provided each with a hopper; said oppers positioned slightly below the top surface of said clay column along the side thereof and registering with the outer terminals of said scraper; said hoppers each provided with a one way valve on the side next to the blower; said blow pipes each terminating under the forward arc of said corresponding rollers whereby the clay crumbs scratched up by' said top surface comb on the clay column may be automat-ically scraped ofl:1 the side7 dropped into the hoppers of said blow pipes where from the action of the blower they are forced out the ends of said blow pipes and discharged forcibly against the edges of said clay column just as said side rollers catch them and presses them simultaneously on both edges 'firmly into said clay column.

i2. In a device of the character described I for teXturing the ends of brick the combination with a set of surface combs and a V shaped scraper for the top surface of a pair of oppositely disposed blowers having blow pipes withopen hoppers registering with the outer ends of said V shaped scraper;

and a pair of oppositely disposed pressure Vof said blow pipes andblown forcibly out of the endv of said pipes into the angle of Contact between said side rollers and the corresponding edges of said clay column where they are automatically rolled firmly into said edges of the clay column thus producing a crummy textured surfaceupon the edges of the clay column where the same may be subsequently severed into building bricks.

3. A process of crummy teXturing the sides of a plastic clay column consisting in mechanically scratching crumbs from the top surface of the column and mechanically blowing said. crumbs against the side of the clay column where they are instantly rolled firmly into thesides of the column before the crumbs have a chance to drop.

ln witness whereof I hereunto set my hand and seal this 28th day of November, 1925.
